| Abstract: The purpose of this paper is to provide a general overview of current and future GNSS and various applications. The role played by the current GNSS in our live is set to grow considerably with new demands for more accurate information along with integration into various applications. The real impact of satellite global positioning on society and industrial development became evident and innovative applications will be available when a GALILEO constellation and modernization of both GPS and GLONASS become operational. There is a need to determine precise ground locations for use in a variety of innovative and emerging applications such as earth observation, rescue applications, and mobilephone technology. Location information is pertinent to a large number of remote sensing applications, some of which support strategic tasks such as disaster management, earth monitoring, protecting the environment, management of natural resources, and food production. With the availability of high-resolution images, some applications will require a location precision down to 1 m. The GNSS provide signals that can serve this purpose. The traditional fields of application for GPS are shipping, aviation, detection, synchronization of telecommunications networks and security of the objects. However, the market is currently enjoying a growth in demand for electronic car navigation systems which make better use of the road traffic network. Automatic Vehicle Location (AVL) and the fleets' management also appear to be growth rapidly. The advents of new satellite systems as well as the modernization of the current satellite navigation systems and the introduction of new frequencies are expected to contribute to the development of new techniques enabling precise positioning with less complexity and lower cost. The majority of satellite navigation applications are currently based on GPS performances, and great technological developments are spent to integrate satellite derived information with a number of other techniques in order to reach better positioning precision with improved reliability, accuracy and availability. With all electronics technologies there is an endless challenge aims to improve the performance of GNSS in signal acquisition, signal tracking, multi-path mitigation and interference rejection while at the same time reducing size, power consumption and cost and adding support for more GNSS constellations. | ||
